The temperature dependence of the luminescence of gamma-irradiated crystals at low temperatures was measured. At temperatures of more than 100 deg C, quartz from different finding places show different curves of thermoluminescence. Measurements were made with strongly colored, colored, and nearly colorless quartz. The specimens were cooled to --196 deg C with liquid nitrogen. They were garnma-irradiated with Co/sup 60/ for 20 minutes at a dose rate of 300,000 r/hr. Subsequent1y, the specimen in question was heated to +100 deg C at a constant rate of 2.6 deg C per minute. Besides the high-temperature maximum, luminescence showed also a low-temperature maximum which indicated the existence of a number of shallow trapping levels. It was found that specimens assuming a color under the action of gamma-irradiation emit a more intense radiation than the colorless specimens. (OTS)
